The new wave of intolerance in Pakistan has been due to Islamisation and Arabicisation of the country. Muslims in Pakistan has changed Urdu and Punjabi so much that it is hard to understand for Indian speakers of these languages. All languages have been Islamised in Pakistan, not just these two.

And it is not just because of hate of
Hindus and Sikhs either. Even 'Pushto' language of Pakistan now
differs from 'Pushto' language of Afghanistan. Pakistani Muslim
fanatics love Arabic so much that they keep replacing original words
with Arabic ones. Even Persian words have been replaced by Arabic
Words. Only original words that they could not find in Arabic have
not been replaced.

Hindus had gone against Foreign Words
also and a lot of Urdu words were replaced with their equivalent
unknown Sanskrit words. Until people of the Sub Continent overcome
their Religious Prejudice and hate of Foreigners this would continue.
Pakistani Muslims are a few times more prejudiced than Hindus, Sikh
and Indian Muslims and their tilt to Islam is the main cause of all
this hate.

They are not only Islamizing languages,
they are even Islamizing Sikh and Hindu names of streets,
neighborhoods, villages, towns and cities.
